SPINNING-HEAD.

Application filed April 17,}914. Serial No. 832,465.

- a description, reference being had to the acadapted to cc-mpanying drawings, which are a part of this specification.

This invention relates to improvements in spinning heads more particularly adapted for use in the manufacture of paper bottles.

It is one of the objects of the present in- Vention to provide a spinning head which is spin the bottom edges of paper bottles over the flanges of flanged bottoms insr rted in the bottles' A further object of the invent1on 1s to provide a spinning head having means for positioning the flanged bottoms Within the bottles a predetermined distance to pro erly turn the bottom edge of the bottle t ereover to form atight closure.

A further object of the invention is to provide a spinnin head having means for adjusting depth 0 the edge of the inaterlal to be spun over the flange of the bottom inserted in the bottle and also for adjusting the thickness of the spun portion.

With the above and other objects in view the invention consists 'of the improved spin ning head and its parts and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views: Figure 1 is a top View of the improved spinning head;

ig. 2 is an inverted view thereof; Fig. 3 is a sectional view thereof taken on line 33 of Fig. 1, the view also showing a sectional view of a part of a paper. bottle engaged by the head; Fig. 4 is a similar View; thereof after the edge of the bottle .has been spun over the flange of the flanged bottom in serted in said bottle; and Fig. 5 is a detail view of a portion of ing manner of adjusting he thickness of the spun portion of the bottle.

Referring to the drawing the numeral 8 indicates a portion of a revoluble shaft and q the improved spinning head mounted thereon. The head is of annular form and I Specification of Letters Patent.

the spinning head show- Patented Dee. Y, 1915.

is provided with a' projecting a set screw 11 for clamping it to a shaft. The Working face 12 of the head is provided with an annular spinning groove 13,

hub 10 having.

an annular bottom positioning portion 14 and a medial recess 15 having openings 16 extending through the head. he annular portion 9 of the face of the head between the spinning groove and the outer periphcry of the head is beveled inwardly toward the groove to form an easy entrance for the bottle edges.

The bottom positioning portion 14 of the head is so spaced with relation to the depth of the flange 17 of the bottle bottoms 18 as to push the bottoms 18 into the bottles 19 a sufficient distance to permit the edge of the bottle to b tom and portion. Adjustable spinning plugs 20 inserted in plug openings 21 provided in the head, intersect the spinning groove 13 and are spaced equi-distantly apart circumferentially. These plugs are provided with transverse grooves 22 of the same width as the spinning grooveof the head and are shaped to conform with the said spinning groove.

e plugs are revolubly and endwise adjustably held in the head are threaded through and impinge against the plugs. The plugs are also provided with slotted ends 24 for gimvenience in adjusting the plugs revolu- The head is adapted to be used in the ordinary manner and will spin the edge of the bottle over the flange of the inserted bottom when the head is revolved and pressed against the edge of the bottle. The bottom positioning part will force the bottom in- Wardly while the bottle edge is being spun over the bottom flange thus insuring a perfect closure. 1

.If it is desired to regulate the depth of the edge to be turned over the plugs may be adjusted endwise to the desired extent and if it is found that the spinning groove is too wide for the thickness of the edge to be spun over the plugs may be revolved to irontract the groove in the manner shown in The medial recess and the to terminate close to the bottom communicating e spun over the flange of the botby set screws 23 which openings serve to permit the escape of air 7 and prevent suction While. the head is in operation.

From the foregoing description it will be seen that'the head is of very simple con- .struction and is,-well adapted for the purpose described.

What I claim as my invention is:

1. A spinning head, comprising a member provided with a plurality .of spaced openings, and grooved plugs revolubly'and endwise adjustably positioned in said openings for adjusting the operative width and depth of the grooves with reference to the member, the grooves of said plugs being in circumferential alinement with relation to each other.

2. A spinning head, comprising a revoluble member provided with a circumferential groove in its working face and a plurality of openings communicating with the groove, and grooved plugs revolubly and endwise adjustably'positioned in said openings for adjusting the operative width and depth of said circumferential groove, the grooves of said plugs registering circumferentially with the groove of the member.

3. A spinning head, comprising a revoluble member provided with a circumferential groovein its working face and a pluralityof spaced openings communicating with the groove, a portion of the revoluble member Within-the line of the groove being formed to position bottle bottoms within bottles, and grooved plugs revolubly and endwise adjustably positioned in said openings for adjusting the operative width and depth of said circumferential groove, the grooves of --ble member provided said plugs registering circumferentially with the groove of the member.

4. A spinning head, comprising a revoluwith a circumferential groove in its working face and a plurality of spaced openings extending through the member and communicating with the groove, the face of the member between the groove and the outer edge of the member being beveled inwardly toward the groove, a portion of the face of the revoluble member within the line of the groove being formed to position bottle bottoms Within bottles, grooved plugs revolubly and endwise adjustably positioned in said openings for adjusting the operative width and depth of said circumferential groove, the grooves of said plugs registering circumferentially with the groove of the member, and set screw for holding the plugs in adjusted positions.

5. The combination with a curling die having an annular groove in one face thereof, of a plurality of pins in said die having grooves in the ends thereof corresponding in shape to the groove in the die, said pins being adjustable in a direction substantially parallel to the axis of rotation of the die to adjust the operative depth of the curling die and also being revolubly adjustable to adjust the operative depth of said groove.

In testimony whereof, I aiiiX my signature, 1n presence of two witnesses.
